disable windows attachment manager (file blocking)

If you’re trying to install files that are downloaded from the internet, they might sometimes be by default “blocked” from install unless you take manual intervention. If you have a large installer that has multiple sub installers, this could be a daunting task. The following group policy edit has worked for me (redownload or re-extract the files that are being setup following doing so):

  • Win Key + R
  • Type “gpedit.msc”
  • Navigate to User Configuration > Administrative Templates > Windows Components > Attachment Manager
  • Enable “Do not preserve zone information in file attachments”
